In this paper, a Bond Graph fault diagnosis methodology applied to a three-phase inverter is presented. A qualitative approach is used, which is based on signal amplitude behavior analysis when a fault in the system is presented. For a complete Bond Graph modelling of the three-phase inverter, sub-models for each power switches are used. Considerations about switching devices from the Bond Graph point of view are made in order to cope the simulation aspect and, at the same time, to avoid causality problems in the qualitative analysis done.
